摘要：
In this presentation, I will introduce a new color basis system and confinement mechanism for 
multi-quark systems according to the string-type picture of QCD. The color string configurations
in the strong coupling QCD are implemented in the set of color basis states. The extended color
Hilbert space for QQQ ̅Q ̅ systems includes a ``hidden color‘’ state, which mixes with two-meson
states QQ ̅+QQ ̅. This mixing effect leads to an attractive potential sufficient to form a bound
state. We apply a realistic Hamiltonian model with the new scheme to fully charmed tetraquark 
states, ccc ̅c ̅, and find a bound and two resonant states, which could potentially correspond to
the ccc ̅c ̅tetraquark candidates recently observed in experiments. The results will be compared 
with the conventional confinement potential which is taken as the sum of the two-body color-
dependent linear potentials.
